How to save vector images in grayscale

Hi, I’m using Aspose.Imaging.

I want to convert the color of an emf vector format image to grayscale in the vector format and save it, or I want to save it as a CMYK value (CMYK for printing instead of RGB). How do I do this?

Best regard.


I regret to share that we do not support vector image to Grayscale. We only support conversion of raster image to Grayscale.

Thank you very much for your reply.

In vector format, it does not support grayscale. understood.
I have seen various many, but I think that none of the vector images are weak to CMYK.
In particular, for barcodes and PDFs, the Phase of printing is mainly involved,
Are there any plans to expand the functionality about the handling of vector format and CMYK in the future?

As we are looking for comparison with other companies’ products, it will be helpful if you can hear about future plans.

Best regard.


Currently we do not support grayscale vector images, but it could be processed using conversion to raster grayscale, for example png, then saving to Vector format.

At the moment it is not in our roadmap. However, we are going to discuss this internally in next week and will share the feedback accordingly with you.
